Abstract: An elongated wood structural member or beam (10) for bearing predetermined loads (16) transverse to the lengths (54) of the members preferably includes multiple elongate wood segments (12) bonded together with their lengths generally aligned with the beam length as in a glue-laminated members. The predetermined load corresponds to a resisting moment that produces compressive and tensile stresses in the structural member in respective compression (18) and tension (20) portions of the beam on opposite sides of a neutral axis (22). A synthetic tension reinforcement (28) having multiple synthetic fiber strands held within a resin matrix is adhered to at least one of the wood segments in the tension portion of the structural member and is selected to be substantially capable of bearing the tensile stress produced by the resisting moment and cooperates with the wood segments to position the neutral axis within the beam. As a result, the width and depth of the structural member and relative positions of the neutral axis and reinforcement (29) may be selected to establish a compression portion of the structural member in which compressive stress from the resisting moment does not exceed a predetermined maximum compressive stress.

Inventor: FINLEY JAMES J
IPC: C03C17/36
Filed: 1997-01-14
Abstract: Amorphous metal oxide barrier layers of titanium oxide, zirconium oxide and zinc/tin oxide are effective as alkali metal ion barrier layers at thicknesses below 180 Angstroms.  The amorphous metal oxide barrier layers are most effective when the density of the layer is equal to or greater than 90% of the crystalline density.  The barrier layers prevent migration of alkali metal ions such as sodium ions from glass substrates into a medium e.g. electrolyte of a photochromic cell, liquid material of a liquid crystal display device contacting the glass surface.  The properties of the medium, particularly electroconductive metal oxide coatings, are susceptible to deterioration by the presence of sodium ions migrating from the glass.  One technique to obtain the desired density of the barrier layers is to provide shields upstream and downstream of the cathode to limit the deposit of sputtered material to sputtered material traveling along a path generally normal to the surface being coated.

Title: Method of and apparatus for interference rejection combining in multi-antenna digital cellular communications systems
Inventor: BOTTOMLEY GREGORY E
IPC: H04B7/26
Filed: 1995-07-28
Abstract: A digital radio communications system is presented in which the deleterious effects of fading, time dispersion and interference found in the channel are mitigated by using interference rejection and diversity combining. Digital signals representative of digital symbol sequences are transmitted through a radio channel in which the signals may be corrupted by fading, time dispersion and interference. The corrupted signals are received by a receiver having one or more antennas. The received signals are processed to form a received signal sample stream rd(kTs) for each of the antennas. Estimated received signal samples for each of the antennas are produced by combining hypothesized signal sequences and models of each channel. The received signal samples and the estimated received signal samples are processed in conjunction with an estimate of the impairment correlation properties to produce branch metrics to be used by a Viterbi, or other sequence estimation, algorithm. The branch metric processor may assume one of several configurations depending on whether or not the channel is time-varying.

Patent CA-2210140-A1 (CA)
Inventor: VOHL RAYNALD
IPC: A01G23/091
Filed: 1997-07-10
Abstract: The felling head of the  invention  is operatively installed at the front end of a tractor vehicle, and used for debrushing a brush covered terrain.   It comprises a rigid framework, from which downwardly depends a pair of flat, spaced-apart elongated skates that slidingly rest on the ground and support the framework over ground.  A pair of discoid saw blades are rotatably supported by the frame, with a ground clearance of a few inches relative to the plane of the skates.  The framework is hingedly attached to the tractor vehicle by means of a pair of linked parallel parallelograms forced into a common pivotal displacement, each having four rigid bars hingedly attached to one another so as to form a parallelogram configuration.  A pair of hydraulic cylinders act on the parallelograms and on the frame, so as to allow vertical linear movement of the frame and a distinct vertical pivotal movement thereof.  Thus, when the tractor vehicle pushes the felling head over an uneven ground surface, the elongated skates will be forced under the load of the  framework  to  flatly  engage  the  ground  surface,  and concurrently the saw blades will be forced to remain parallel to the ground surface with a ground clearance.  The felling head further comprises a vertical pivotal axle, to horizontally pivot the  saw blades.   Outwardly  frontwardly divergent  arms  are provided to convergently bias incoming brush towards the central saw blades.

Abstract: A self-standing container (6) with a petaloid base is blow molded from a monobas e preform (18). The monobase preform (18) has a thick reinforcing ring forming portion (24) which remains relatively unstretch ed during blowing. The reinforcing ring forming portion (24) is thicker than both the sidewall forming portion (22) and the bottom formi ng portion (23) of the preform (18). Because the thicker reinforcing ring forming portion (24) has a greater mass per unit area, it is sl ightly cooler than the thinner portions of the preform (18). Therefore, the reinforcing ring forming portion (24) stretches to a lesser degre e than the thinner sidewall forming portion (22) and bottom forming portion (23) during blow molding. The result is a container (6) having a reinforcing ring (21) extending extending circumferentially around the base, an oriented gate area (14) and a petaloid base with at least three, pr eferably five, feet (9).

IPC: F16M13/02
Filed: 1997-08-08
Abstract: A hanging bracket is initially secured to an electric outlet box.  The hanging bracket includes on one of its ends, two canopy hooks with a screw hole located therebetween.  The other end of the hanging bracket includes a single screw hole.  A canopy includes two spaced slots shaped and located to receive the two canopy hooks of the hanging bracket.  With the canopy hooks extending through the corresponding slots in the canopy, a fan assembly is pivotally mounted on the hanging bracket.  It is than possible to connect the lead wires of the outlet box and the wires of the fan assembly.  All that is then required is to pivot the canopy with the associated fan assembly about the canopy hooks into a vertical orientation.  No additional lifting of the fan assembly independent of the fan assembly being supported by the hanging bracket is required.  A single screw is inserted through the canopy into the screw hole in the hanging bracket at the end of the hanging bracket opposite to the and which includes the canopy hooks.  There is an automatic alignment between the hole in the canopy and the hole in the hanging bracket when the fan assembly is pivoted into a vertical orientation.  As another safety precaution, a second screw is inserted through the screw hole in the canopy and into the screw hole in the hanging bracket located between the two canopy hooks.

Patent CA-2217143-A1 (CA)
Title: Positive controls for use in polynucleotide amplification
Inventor: RYNCARZ ALEXANDER JR
IPC: C12Q1/6844
Filed: 1997-01-30
Abstract: The present invention relates to an improvement in a method for amplifying a target sequence of a target polynucleotide. The method comprises the step of forming extension products of an oligonucleotide primer at least along the target sequence or along an extended oligonucleotide primer. The extension products are copies of the target sequence. The improvement comprises forming the extension products in the presence of a second polynucleotide, to which the oligonucleotide primer hybridizes except for 1-10 nucleotides at the 3'end of the oligonucleotide primer. Under the conditions chosen, the oligonucleotide primer is extended along the second polynucleotide in a controlled manner relative to extension of such primer along the target sequence, thus providing a positive control for the amplification reaction, which control may be qualitative or quantitative. Optionally, a modified oligonucleotide primer is included in the amplification reaction. The modified primer is substantially identical to the oligonucleotide primer with the exception of a chemical modification at its 3'-end that prevents degradation, under the reaction conditions, of the 1-10 nucleotides referred to above. The method finds particular application in the area of nucleic acid amplification.
